Cleaning
The instrument should be cleaned often enough to pre vent
dust anddirt from accumulating. Dirt acts asa thermal insu-
lator,preventing effective heat dissipation, and can also pro-
vide high-resistance electrical leaka ge paths between conduc-
tors or components in a humid environme nt.
CAUTION
Do not allow water to get inside any enclosed
assembly or component. Donot cleanany plastic
materials with benzene, toluene, xylene, acetone,
or similar compounds, because they may damage
the plastic.
Exterior

clean cloth or small brush. A brush is especially useful for
removing dust from around the selector buttons, knobs, and
connectors. Hardened dirt can be removed using a soft cloth
dampened witha milddetergent and water solution. Abra-
sive cleaners should not be used.

dampened in denatured alcohol. Abrasive cleaners should
